FFF CompatibilityPins 1-4 and Pin 6 match the original layout, but Pin 5 is VOUT SENSE instead of Noise Reduction (NR). A capacitor populated on Pin 5 must be removed, and Pin 5 must be tied to Pin 6 (VOUT FORCE) for proper regulation.Matches the SOT-23-6 physical dimensions and footprint envelope.Provides a highly precise 1.2V series reference output with low temperature drift.Requires a complete board redesign to switch from SOT-23-6 to a 4-pin WCSP footprint.Physical package type is completely different (Wafer-Level Chip Scale Package vs SOT-23).Delivers the identical 1.2V reference output voltage, accuracy, and nanopower performance.
AI Summary

REF35120QDBVR by Texas Instruments: Series Voltage Reference IC Fixed 1.2V V ±0.05% 10 mA SOT-23-6.

This is a high-precision 1.2V series voltage reference from Analog Devices in an SOT-23-6 package. It offers comparable low drift and high accuracy, but requires minor circuit adjustments because Pin 5 acts as a sense line rather than a noise reduction pin.

  • Available from Analog Devices in the same SOT-23-6 package size
  • Excellent 0.1% initial accuracy and low 8 ppm/°C typical drift
  • Stable over the same industrial -40°C to +125°C temperature range
  • Higher typical supply current of 100 uA compared to the nanopower 650 nA of the REF35
  • Pin 5 requires circuit adjustments (must be tied to Pin 6, noise filter capacitor on Pin 5 must be removed)

This sibling variant uses the same core design but is housed in an ultra-compact 4-pin WCSP package. It is ideal if you are looking to drastically reduce board area, though a complete layout redesign is necessary.

  • Exact same nanopower silicon design and internal specifications
  • Maintains the ±0.05% accuracy and 12 ppm/°C drift baseline
  • Ultra-small 4-pin WCSP footprint (1.05mm x 0.84mm) saves board area
  • Requires complete board layout redesign due to package difference
  • BGA-style mounting is more complex to assemble and inspect than SOT-23

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
